The nurse understands that increasing the flow of oxygen to more than 2 L/min in the client with chronic obstructive pulmonary disease (COPD) could be harmful because it:
1. Is drying to nasal mucosal passages
2. Decreases diaphragmatic excursion and depth
3. Increases the risk of pneumonia and atelectasis
4. Decreases the client's oxygen-based respiratory drive
4
Rationale: Normally, respiratory rate varies with the amount of carbon dioxide present in the blood. In clients with COPD, this natural process becomes ineffective after exposure to high carbon dioxide levels for prolonged periods of time. Instead, the level of oxygen provides the respiratory stimulus. The client with COPD cannot increase oxygen levels independently because this could severely decrease the respiratory drive, leading to respiratory failure.
